Pneumatic wiring?

[jalmos]

Again another post by our rookie team. Attached is a pic for pneumatic part. We are confused to where we wire this to and is there programming involved with it?

our pneumatic system is using a single air cylinder with a double solenoid? to open and close a jaw for our robotic arm. Thanks for your time and help

That's the pressure switch. It opens and closes depending on the sensed pressure. It needs to be wired to a digital input port on the digital sidecar.

Have you read the Pneumatics Manual (http://www.usfirst.org/sites/default/files/uploadedFiles/Robotics_Programs/FRC/Game_and_Season__Info/2012_Assets/2012%20FIRST%20Robotics%20Competition%20Pneumatics %20Manual.pdf) (pdf)? It should answer most of your questions.

That part is the digital pressure switch, which tells your compressor when the air tanks are at full pressure so it can turn off.

You want to wire the switch to an open Digital IO port. You can do this by modifying a PWM cable. Wire the black (-) wire to one end of the pressure switch. Wire the white (Signal) wire to the other end. It doesn't matter which end gets (-) and which gets (signal).

In your code, you will need to tell your compressor VI or function which port the switch is plugged into (which language are you using?)
